Continuously Wound Spiral L Form Finned Tubes
The fin is pre-formed and then tension-wound onto the tube. The L form footprint grips the tube tightly and delivers high efficiency.
On our purpose-built machine for continuously wound spiral finned tube production, the fin is first pre-formed and then wrapped onto the tube under tension.
When carbon steel tube and carbon steel fin are selected, we recommend hot-dip galvanizing to our customers.
There are two main reasons for this: to protect the products against corrosion, and to perfect the heat transfer between the fin and the tube.
Advantages and Disadvantages
- More expensive than the corrugated, I and G forms; in return it offers high efficiency.
- Thanks to the distinctive L form design the fins grip the tube very tightly, giving resistance to thermal cycling and to high-velocity air-induced vibration.
- There is no turbulence, so air-borne noise is very low.
- It is one of the fin profiles used in special applications.
- It does not tend to trap dust or similar particles.
